Horizontal Scrollbar Issue - Narrow Dragging Area

Increasing the width setting of a horizontal scrollbar with a list box did not produce the desired effect,
to spread the scrollbar arrows over a wider area.
As you can see when you run the code, the dragging area is small.
Can the standard tkinter horizontal scrollbar be set up with a larger dragging area?

I could not get your code to run because you are using both tk.Tk() and import *, pick one or the other. In any case the problem seems to be that you pack the scrollbar with fill=Y (would yield a tall/large size on the Y axis) instead of fill=X (or fill='x' depending on how you import Tkinter).

Thanks dwblas for explaining in a way that it first became obvious to me: fill=Y and fill=X are referring to
the Y and X axis, not 'Y' for YES and 'X' for NO. (I would use a lit lightbulb icon here if they had one)

I've edited the code above with the changes you suggested, including the incorrect double importing of tkinter.
